“COM” terminals. Open photocell is connected to “OPN
PHO” and “COM” terminals.
AFTER SENSORS ARE CONNECTED:
1. Turn on power.
2. Make sure the photo-beams are properly aligned per
the manufacturer’s specifications.
3 . Test the
CLOSE
obstruction sensing system for proper
operation, by blocking the beam across the gate
opening while the gate is running closed.
NOTE: The gate should stop and reverse a short distance
and then stop.
4. Run operator to close limit.
5. Test the
OPEN
obstruction sensing system by
blocking the beam mounted at the back area of the
gate while the gate is running open.
